The Common Potoo, Grey Potoo or Lesser Potoo, is a nocturnal bird which breeds in tropical Central and South America — from Costa Rica to northern Argentina and northern Uruguay.
This potoo is a large cypselomorph bird related to the nightjars and frogmouths, but like other potoos it lacks the bristles around the mouth found in the true nightjars. It is 33–38 cm long and pale greyish to brown, finely patterned with black and buff, camouflaged to look like a log; this helps protect it from predators, and aids in its own camouflage when hunting. It has large orange eyes.
The Common Potoo can be located at night by the reflection of light from its eyes as it sits on a post, or by its haunting melancholic song, a BO-OU, BO-ou, bo-ou, bo-ou, bo-ou, bo-ou, bo-ou, bo-ou dropping in both pitch and volume.
It is a resident breeder in open woodlands and savannah, rarely occurring over 1,900 meters instead preferring the gallery forest-type environment around the Uruguayan-Brazilian border. Source
